Viral Membrane Protects Medical Nanorobots From Immune System
Scientists say they have developed a cloaking device to spirit medical nanorobots of the future past immune systems into diseased cells. Their innovation comes from stealing a powerful weapon viruses wield to infect their hosts.
Some viruses wrap themselves in a protective membrane to avoid detection by their host’s immune system and enter cells they are trying to infect. A team at Harvard’s Wyss Institute for Biologically Inspired Engineering have been able to construct their own version of a viral membrane.
Silicified stump: a type of petrified wood in which the organic material was replaced with a silicate mineral - in this case, clear quartz. The process of petrification occurs when organic material becomes quickly buried in a strict, oxygen-free environment, often as a result of flooding or volcanic eruption.
This specimen comes from the Gallatin Petrified Forest in Yellowstone National Park, an ancient Eocene ecosystem which thrived between 55-35mya. Check out this beauty on display in the newly configured geology exhibition space on the 2nd floor at The Field Museum!
